2 Claims. (Cl. 126-85) families are adding such space to existing homes by either building into garages, attics or the like, or by building completely new extensions.

One of the basic problems inherent in the above type of construction is the provision of adequate heating. It is often found that the extension of the existing heating system to the added rooms would be impractical and unduly expensive because of the requirement of new ductwork in the walls and the provision of a larger heating unit. Consequently, most people who build these additional rooms have merely provided an individual heater for the added room, such heater being.completely separate and distinct from the main heating system.

These individual heaters usually take the form of separate electric or gas heaters either placed within the room or built into the walls. However, they detract from the appearance of the room and occupy space which might otherwise be utilized for either functional or decorative purposes.

The majority of the added rooms mentioned above are used as dens or family rooms and, in many cases, are

ecorated in a rustic fashion. This type of decor lends itself to the use of an old-fashioned wood-burning type of pot-bellied stove. However, the inconvenience and inefficiency of such wood-burning stoves makes them irnpractical for use in the modern home.

It is one object of the present invention to overcome the above-noted disadvantages of wood-burning stoves while retaining the decorative features thereof by providing a pot-bellied type of stove which operates on gas rather than wood or coal.

Another object of the present invention is to provide a stove of the aforesaid type which is simple in construction and which is easily used and maintained in operating condition. 7

Other objects of the present invention are to provide an improved heating device, of the character described, that is easily and economically produced, which is sturdy in construction, and which is highly efficient in operation.

With the above and related objects in view, the present invention consists in the details of construction and combination of parts, as will be more fully understood from the following description, when read in conjunction with the accompanying drawing in which:

FIG. 1 is a side view, partly in section and partly in elevation, of a stove embodying the present invention.

FIG. 2 is a cross-sectional view taken on line 22 of P16. 1.

FIG. 3 is a cross-sectional view taken on line 3-3 of FIG. 1.

Referring in greater detail to the drawing wherein similar reference characters refer to similar parts, there is shown a stove, generally designated 10, comprising a body 12 having an upper chamber 14 and a lower chamber 16, the body 12 comprising two frusto-conical portions 11 and 13 open at both their ends and having the larger ends of both joined together.

Within the upper chamber 14 is a tubular baflle member 18 which has a cylindrical side wall, a bottom wall 19 and is open at the top at 21. Inturned baffle flanges 20 surround the baflle member 18 and are secured to- "ice gether through an annular skirt 22 depending outwardly of the body 12, the skirt acting as a bathe to outwardly deflect air that has been heated by the lower frusto-conical portion 13 of the stove body 12, and also as a handle for carrying the entire device when transporting it to a desired location.

A hinged door 24 is provided on the body 12 in the area of the upper chamber 14 to provide access to the chamber 14.

The baffle member 18, as stated above, is open at the top at 21, and this open top 21 is aligned with and spaced slightly below a flanged opening 26 in the interior of the stove body coinciding with a similar opening in the bottom of the stove top and leading through a burned gas passageway. The passageway from the opening 26 is, in turn, connected through stove top 27 and its stack opening 29 with an exhaust pipe or stack 28 adapted to lead out of the room to atmosphere or a chimney. The diameter of opening 26 in the inturned flange at the top of frusto-conical portion 11 is thus slightly less than the diameter of tubular baffle member 18, thus increasing the heat transfer from the burned gases to the inner surfaces of the stove portions.

Extending from the opening 30 provided in the bottom wall 19 of the baffle member 18 is a support tube 32. This support tube 32 extends down into the lower chamber 16 and is there supported on the center 34 of a star type gas burner 36.

The burner 36 is connected to a horizontal gas and air mixer 38. The gas burner 36, including its center portion 34 and surrounding portion having the gas flame openings 37, extends into the circular opening 15 in an intur'ned flange 17 on the top of lower chamber 16, the circular opening 15 coinciding with a similar opening 21 in the bottom of lower frusto-conical stove body portion 13. This mixer 38 is connected through an elbow 40, pipe 42 and elbow 44 to a pipe 46. The pipe 46 is coupled at 48 to an elbow 50 which is, in turn, connected to a manually operable valve 52. The valve '52 is connected through a standard type pilotstat safety valve 54 and through an elbow 56 to a pipe 58. The pipe 58 is connected to an ordinary gas inlet 60 through a gas cock 62. The safety valve' 54 is connected by tube 64 to a pilot burner 66. It is also provided with a standard type thermocouple regulatory device (not shown) in circuit with the pilot burner.

A hinged door 68 is provided at the front lower portion of body 12 to give access to lower chamber 16 and particularly to the burner 36 and valve 52. This door is provided with the ordinary adjustable damper opening 70. The entire stove is supported on legs 72.

The function and operation of the above-described stove is obvious from the description. It should be noted, however, that the baflle tube 18 acts to hold the largest percentage of the heat generated in the stove within its central portion so that the heat radiation into the room comes from a concentrated and, therefore, more effective heat source.

The heater may be turned off either manually, as by use of the valve 52, or automatically when the pilot flame goes out. This automatic, safety control is provided by valve 54.

Although this invention has been described in considerable detail, such description is intended as being illustrative rather than limiting, since the invention may be variously embodied, and the scope of the invention is to be determined as claimed.

Having thus set forth and described the nature of this invention, what is claimed is:

1. A gas heating device comprising a pot bellied stove body circular in horizontal cross-section and a base chamber member square in horizontal cross-section, and

base supporting legs at each bottom corner of said square fir usto conical portions, said base chamber having an inturned flange on its upper side having a circular opening therein coinciding with an opening at the bottom of the lower frusto-conical portion, a gas burner in said base chamber, said gas burner comprising a center portion and a surrounding portion having gas openings, said surrounding portion extending into said circular opening "of said base chamber flange, a support tube secured on said burner center portion, a circular baffle plate supported on said support tube approximately midway of said lower frusto-conical stove body portion, a tubular baffle member secured on said bafiie plate and extending upwardly through said coinciding connecting openings of said irusto-conical stove body portions to close to but spaced from the top end of said upper frusto-conical stove body portion, said bathe plate and said tubular baflle member deflecting the burned gases from the gas burner toward the inner surfaces of said frusto-conical stove body portions, an inturned flange at the top end of said upper frustoconical stove body portion having an opening of lesser diameter than the diameter of said tubular baffle member,

a stove top having an open bottom mounted on said open top end, said stove top having burned gas passage means leading to an exhaust stack opening thereon.

4r 2. The gas heating device of claim 1, said frusto-conical stove portions having inturned flanges at their joined ends and said annular skirt extending between said inturned flanges, said coinciding connecting openings of said frusto-conical stove portions being in said inturned flanges and extending through said annular skirt, means extending through said .inturned fi-anges and said annular skirt securing said stove portion flanges and said skirt together, said inturned flanges providing additional burned gas bafie means within said stove body portions to increase heat transfer to said stove body, said annular skirt providing outside heated air deflecting means and handle means when transporting said heating device.
